基于电网模型的地理信息可视化实现

电网模型是描述系统全局运行状态的数据文件,针对ARC/INFO平台图形显示局限于离线关系数据库的现状,提出可交互电网地理信息可视化的实现方法。在研究CIM/XML模型文件作为电网地理参数的数据载体的基础上,通过关联的元件类来表达电力设备的实际属性,设计ODE接口的外部操作环境,实现电网拓扑关系的创建以及图形元素的绘制与显示。结合综合数据平台的在线应用表明,该方法有效减轻系统维护工作量并对电网实时运行表达有较高的准确度。

Realization of Geographic Based on Power Information Visualization Network Model

Power network model is the data file which describes the overall operation status. Considering ARC/INFO platform graphical display is limited to the off-line relational database, an interactive geographic information visualization based on power network model is introduced. Based on the study of CIM/XML model file as grid geographical data carrier, associated component classes is used to express the actual property of power equipment, and through designing external operational environment of ODE interface, the gird topological relations are created as well graphical element is depicted and displayed. A comprehensive data platform with the online application shows that the method is effective to reduce the workload of system maintenance and run a higher overall accuracy.
